Nissan designed the sixth-generation 2019 Altima to fulfill a lofty mission: shake up the midsized sedan segment. The carmaker said it was already well into work on its formerly best-selling vehicle when the Rogue crossover became the most popular Nissan on the lot. Once the Altima had been freed from the constraint of being the company's No. 1 in the U.S., Nissan decided to go further with the Atima's design and detailing, and make it a global car. The result sits on a new platform, gets two new engines, a lot more tech, and is available with all-wheel drive.
Trim count increases to five: S, SR, SV, SL, and the new Platinum. The standard engine in every trim is a 2.5-liter four-cylinder with 80 percent of its parts either new or redesigned compared to the current 2.5-liter four. Changes include adding direct injection, integrating the exhaust manifold into the cylinder head, and a thermal insulated resin intake port, which uses an air layer to help keep fresh intake air cold. Power goes up nine horsepower to 188, torque rises three pound-feet to 180. Fuel economy and refinement see upgrades as well.
